Mycobacterium paratuberculosis (also called Mycobacterium avium subspecies paratuberculosis) is a significant cause of morbidity in dairy cattle in many countries, and infected animals may shed high levels of the organism in their faeces and low levels in milk. The IDF M. paratuberculosis Task Force comprised of 33 experts from 18 countries and diverse fields of specialization. Its objective was to compile information on the current practices, knowledge and research related to M. paratuberculosis and to assess available strategies for controlling M. paratuberculosis and where significant gaps in knowledge about this organism exist.
The report presented in this Bulletin contains five chapters, each addressing a specific objective assigned to the Task Force:
1. Diagnostic tests for paratuberculosis in cattle.
2. On-farm paratuberculosis control methods.
3. Ecological characteristics of M. paratuberculosis (factors affecting survival outside the host).
4. Methods for enumeration of viable M. paratuberculosis in milk and milk products.
5. Destruction of M. paratuberculosis in milk and milk products by heat.
